Specification of Letters Patent.

Application filed January 19,1906. Serial No. 296,791-

To all 1072,0112. it may concern.-

Be it known that I, JOHN W. BARLOVV, a citizen of the United States, residing at Kansas City, in the county of Jackson and State of Missouri, have invented certain new and useful Improvements in a Combined Journal and Lubricator, of which the following is a specification.

This invention relates to dust-proof journals and lubricators, and more especially to journals of this character for agricultural implements.

The object of the invention is to produce a journal having only a single point or line of communication with the atmosphere and from which the lubricant eventually escapes and in such escape prevents the entrance of dust and dirt.

A further object is to produce an efficient and reliable journal of the character named which is simple, strong, durable, and cheap of construction.

To these ends the invention consists in certain novel and peculiar features of construction and organization, as hereinafter described and claimed, and in order that it may be fully understood reference is to be had to the accompanying drawings, in which Figure 1 is an enlarged central vertical section of a dust-proof journal and lubricator embodying my invention, taken on the line I I of Fig. 2, said figure also showing a disk secured to a part of the journal. Fig. 2 is an inner face view of the same. Fig. 3 is a section on the line III III of Fig. 1 and on the same scale as said figure. Fig. 4 is a side view of the journal equipped with a disk.

In the said drawings, 1 indicates an axle projecting at one end into a cap 2 and secured therein by the engagement of lugs 3 and cavities 4, the cavities being in the axle and the lugs integral with the cap, which latter by preference is cast upon the axle. The cap is provided with a circular flange 5, provided with a plurality of poles 6, and 7 indicates a circular recess formed in the inner face of the cap, which face when the cap is used in connection with cultivating or plowing disks is usually concave, as shown in Fig. 1.

8 indicates a hollow and preferably cylindrical sleeve closed at its inner end and provided at its outer end with an outwardlyprojecting annular flange or enlargement 9.

At its inner end the sleeve is preferably pro:

vid ed in its upper side witha threaded passage 10, wherein is tightly secured the threaded stem of a cup 11, the upper end of said cup being externally threaded, as at 12, for engagement by the internally-threaded cap 13.

14 indicates a disk of the type generally used on cultivators, provided with a series of holes 15 corresponding to holes 6.

To assemble the parts together, the closed end of sleeve 8 is passed from the convex side through the hole 1 1 in the center of the disk until arrested by the flange or enlargement 9 striking against the disk. The axle is then slipped into said sleeve until the circularrib 16, projecting into recess 7 and cast with the cap, bypreference comes in contact with the outer end of the sleeve, the axle being preferably of such length that its inner end does not cover or underlap the opening 10. Bolts 17 are then passed from the inner face of the disk through the holes 15 thereof and holes 6 of the flange 5 of the cap, clamping-nuts 18 being then secured upon the outer end of said bolts to clamp the disk and cap reliably together, so that they shall be capable of revolving around the enlargement or collar 9 of the sleeve. The cup 11 and cap therefor are fully clarged with the lubricant, in plastic state by preference, and then the cup is screwed home in passage 10. The cap 13 is then screwed upon the cup, so as to force a part of said lubricant into the inner end of sleeve 8, outwardly around the axle, and into recess 7, the cap being screwed sufficiently upon the cup to eventually force the lubricant completely around the enlargement or collar 9 and through the hole 14 of the disk, which, it will be noted, is the only exit for the lubricant or inlet for dust, dirt, and other foreign particles.

In practice the dirt which is raised by the disk and falls upon the sleeve does not pass through hole 14 because the latter is always charged with the lubricant. In fact, this lubricant is oozing constantly but imperceptibly through said hole and in conjunction with the small volume of dirt which falls on the sleeve conti uous to the disk produces a gummy ring of dirt which most effectively cooperates in preventing the entrance of dust and dirt to the journal. At suitable periods the cap 13 is screwed further upon the lubribeing understood, of course, that the part 14 may be a rotary device of other type than that shownthat is to say, it may be a carrying-wheel for travel upon the ground instead of a device for producing a furrow, as in a plow, or for turning the soil, as in a cultivator.

From the above description it will be apparent that I have produced a dust-proof journal and lubricator possessing the features of, advantage enumerated as desirable in the statement of the object of the invention and which obviously may be modified in minor particulars without departing from the principle of construction involved.

Having thus described the invention, what I claim as new, and desire to secure by Letters Patent, is-

1. In a device of the character described, a cap provided at its inner side with an axle and a recess surrounding said axle a sleeve journaled on the axle and having one end occupying said recess, and a rotary .device secured rigidly to said cap and having a central hole or opening surrounding the sleeve and holding that portion of it occupying said recess reliably within the latter.

2. In a device of the character described, a cap provided at its inner side with an axle and a recess surrounding said axle, a sleeve j ournaled on the axle and provided with an enlar ement occupying said recess and a rotary device secured to said cap fitting on the sleeve inward of said enlargement.

3. In a device of the character described, a cap provided at 1ts inner s1de with an axle and a recess surroundmg said axle, a sleeve journaled on the axle and provided with an enlargement occupying said recess, a rotary device fitting on said sleeve at the inner side of the enlargement thereof and said cap, bolts extending through said disk and cap, and retaining devices engaging said bolts and clamping the disk and cap tightly together.

4. In a device of the character described, a cap provided at its inner side with an axle and a recess surrounding said axle, a sleeve j ournaled on the axle and having one end occupying said recess, a rotary device secured rigidly to said cap and having a central hole surrounding the sleeve, and holding that portion of the latter occupying said recess reliably within the same, and means for forcing lubricant into said sleeve.

5. In a device of the character described, a cap provided at its inner side with an axle and a recess surrounding said axle, a sleeve j ournaled on the axle and having one end occupying said recess, a rotary device rigidly secured to said cap and having a central hole surrounding the sleeve, and holding that portion of the latter occupying said recess reliably within the same, a cup carried by and adapted to discharge into said sleeve, and an adjustable cap closing said cup.

6. In a device of the character described, a cap provided at its inner side with an axle and a recess surrounding said axle,a sleeve j ournaled on the axle and having one end occupying said recess and having its other end closed, a rotary device secured rigidly to sa d cap and having a central hole surrounding the sleeve and holding that portion of the latter occupying said recess reliably within the same, a lubricant-cup carried by and adapted to discharge into said sleeve, and a cap for said cup.

In testimony whereof I affix my signature in the presence of two witnesses.

JOHN W. BARLOW.
